Changelog

Version 1.0.0.0 - 2015/03/13

Additions and Improvements

Added Tweet Text filter system (exclude tweets from being displayed based on their content)

Added Tweet User filter system (exclude tweets from being displayed based on the user)

Added Pause option (Right-click tray icon > Pause Twittalert)
Which will allow you to temporarily stop Twittalert from displaying new Tweet notifications.
Or allow you to stop currently displayed tweets from disappearing and disable their topmost nature.

Added 'Notification position' option to choose which corner of the screen to display notifications in

Added 'Notification cut-off point' option to mask off a part of the screen where notifications should fade out

Added 'Custom sound file' option to change the default sound that is played whenever a new notification is displayed

Added 'Overal volume' option to change the overal volume of sounds produced by Twittalert

Streamlined notification action buttons (replaced text with icons)

Added Retweet and Favourite counters of tweets to notifications

Tweaked behaviour of double clicking on Twittalert's tray icon to open the "All Tweets" list, so that this action can also be used to close any notifications or lists that may allready be open.

Tweaked behaviour of priority applications, so that notifactions are only held back when the application is actually being used

Fixes

Added a maximum height for notifications (so a single notification can't cover the entire height of the screen, and therefore clipping of the close button)

Fixed an issue where new notifications would be displayed on top of the mediaviewer if it was allready open at the time of displaying the new notification

Improved UpdateInstaller code to be able to handle slow releasing file locks better

Tons of under the hood improvements

Version 0.0.6.1 - 2014/08/02

Fixes

Fixed a display problem when using Twittalert on a system with an increased DPI setting
(Notifications will now be positioned properly instead of being cut off or completly out of the screen area due to the DPI scaling)

Fixed a bug in Notification's tweet content.
(Links to embedded @mentions would use to the user's Display Name instead of their Account Name
Therefor linking to an incorrect/inexisting Twitter profile page, this has now been fixed)

Version 0.0.6.0 - 2014/07/12

Additions and Improvements

Added the ability to download images embedded in Tweets directly from within the notification or fullscreen viewer (right-click on image > Download media)
Feature request by Asen Anastassov

Added the ability to log yourself off from within the application (and log in as a different user)

Added explicit support for media site: vine.co/v/

Added code to help bring the tweets viewer to the foreground when opening

Version 0.0.5.9 - 2014/06/22

Fixed a UI bug where the Autorun setting checkbox would display a checked state, implying this setting is enabled even if it was disabled.
(Although the checkbox would always display the setting as enabled, in this case the actual setting would still be enabled/disabled whenever the user changed this setting)
Thanks to Asen Anastassov for reporting this bug

Version 0.0.5.8 - 2014/06/14

Additions and Improvements

General code cleanup

Fixes

Fixed a bug where Twittalert would not initiate the authorization procedure when an authorization file existed but didn't contain valid credential data

Additions and Improvements

Added following settings (Access from Tray icon > Settings):

Run when windows start (Autorun when you turn on your PC)

Application filter (prevent notifications froms popping up when a certain application is running)

Isolated even more loading functions from UI thread to a Worker thread (increase speed and improve responsiveness)

Redesigned (Favourites/All) Tweets viewer to load tweets more effeciently and more user friendly
Only the first tweets are loaded initially, while the rest will be autoloaded when needed

Improved zooming and scrolling functionality

Added ability to switch from zooming to scrolling by simply holding the SHIFT key

Added ability to reset the zoom percentage back to 100% (original size) by pressing the middle mouse button

Added more intelligence to the zooming behaviour by zooming at the focus point (mouse position)

Tweaked the opening of links from the application, to make sure they always open in the default browser
+ Added a mouse cursor indicator when launching the browser to provide visual feedback to the user that the link is opening (for slower machines/browsers)

Restyled scrollbars in the media viewer to match the application style

Fixed a rare bug in the Tweets viewer which in some cases caused the Tweets viewer to only show after a long delay

Fixed a design bug in the media viewer, causing the window not correctly fitting the screen (therefor hiding horizontal scrollbar when needed)

And other smaller bugs
